GALVANIC BATTERY.

'SPBCIFICATION forming part of Letters Patent No. 321,446, dated July 7, 1885.

Application filed January 16, 1885.

To ctZZ wit/0722, it may concern:

Be it known that I, Crmntns PARKER 013313, of Cambridge, in the county of Middle sex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Galvanic Batteries; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a side elevation, and Fig. 3 a transverse section, of a battery of my invention, the nature of which is defined in the claim hereinafter presented.

In such. drawings, A denotes a glass or lead cup orvcssel having extending down Within it an earthenware or porous cup, B, and entirely around such a packing, E, of lumps of gasretort carbon, such packing nearly filling the space that is within the two cups and around the inner one. ithin and extending above the porous cup B is a stick or mass, D, of zinc, from which one circuit-wirc is extended. A stick of gas-retort carbon, C, from which the other wire, I, projects, is also extended down into the packing E of lumps of such carbon, and projected, as shown, above the top of the vessel A. On top of the said packing E of lumps of gas-retort carbon, and surrounding the porous cup and extending from it through out the annular space between it and the upper part of the vessel A, is a layer, of paraffine-wax or gutta-percha, through which a hole or holes, G, are made from its top to its bottom. The upper surface of the layer of para'tline-wax Iprct'er to make trouglrshaped or inclining, as represented, in order to readily conduct to the holes Gr an acid solution when poured on top of the said layer. The said layer of parat'iinc-wax or guttapcrcha, byadhering closely to the outer periphery of the cup B and to the inner circumference of the vessel A, keeps the carbon packing, the stick of carbon, and the porous cup in place,when the whole may be inverted for the purpose of discharging from the vessel A through the .hole or holes G any spent acid solution.

The porous cup and the space containing the packing of gas-retort carbon are to be charged with a suitable acid solution-such as is generally employed in galvanic batterieswhich having been done, the battery will be ready for operation, as other kinds are generally used.

I employ in a state of lumps the packing of gas-retort carbon, in order that it maypresent (No model.)

to the action of the acid solution a greater surface than a simple solid packing of carbon of like size would. The packing should not be employed in a comminuted state or as in fine powder, such not being so eilective as when it is in a state of lumps. The layer of parafiine-wax is indestructible by the acid solution, and serves not only the purposes be fore mentioned, but as a scaling for the vcssel A.

To supply the vessel A and its packing with the acid solution, the latter is to be poured upon the upper surface of the layer ot'parafline, in which case such solution will run through the hole or holes G, and thence into the spaces between the lumps constituting the carbon packing.

Such a battery has been found in practice to be reasonably efficient, it being easily relieved of the acid solution by inverting it,

when occasion may require, in which case the parts of the batteries will retain their normal positions.

I do not claim, in an electrical storage-battery, a porous cup surrounded by and having carbon within it; nor do I claim a galvanic battery having in its porous cup a mass of carbon, and in an acid solution outside of the cup a quantity of zinc; nor do I claim a battery, as described and represented in the United States Patent No. 175,884, in which a perforated stoneware or non porous diaphragm or cell constitutes an. essential ele ment of the invention, and such has a stopper and a filling opening or tube extending through such stopper, for I employ a porous and unpertorated cell, open at its top, and I have around such and within the outer cell or vessel and on the mass of gas-retort carbon therein a layer of parailine -wax, having a hole or holes through it for supplying the mass with the excitingsolution.

I claim- The improved galvanic battery, substantially as described, consisting of the glass or leaden vessel A, the porous cup B, the stick 0 of carbon, the stick D of zinc, the packing E of lumps of gas-retort carbon, and the layer f of paraliine-wax or guttapercha having one or more holes, G, in it, all arranged essentially as set forth.
